Question 2 If a map does not contain the targeted key, then the get method: Throws a MapUnderflow exception. Adds the targeted key to the map. Returns null Does nothing. None of these is correct. Question 3 This implementation approach supports an efficient, i.e., O(log2N), implementation of the map’s contains and get operations: unsorted array sorted array ArrayList. linked list. sorted linked list. Question 4 A hashing approach: will often support constant time storage and retrieval of keys. only works if the keys are integral. is guaranteed to provide O(1) storage and retrieval of keys. is typically very space efficient. None of these is correct Question 5 A typical hash function often consists of the following three steps: hashing, compressing, and indexing. multiplication, addition, and modularization. selecting, digitizing, and combining. modularization, probing, and indexing. compressing, hashing, and probing. Question 6 Our HMap class uses: linear probing. quadratic probing. buckets chaining. None of these is correct.
